To cZZ whom 7123 may concern:

Beit known that I, EDWARD SENDELBACH, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Vehicle-Hubs; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form apart of this specifica tion.

LNIy invention relates to huhs; and it consists in a wooden hub providedwith metallic shells covering its ends and secured to the hub by animproved fasteniug.

In certain kinds of Vehicles the trade in sists on having a hub whichretains the shape of the old woodeu hub, but has its ends covered withmetallic shells to prevent checkin g of the Wood, leaving the centralportion of the wooden hub exposed where the spokes are driven in, so asto afford a wood cushion at the joint. Heretofore this style of hub hasgiven poor satisfaction, especially in hot climates, for 'the reasonthat there was no way of permanently holding the shells on the hub.Screws and nails would work loose and come out. Moreover, their headscould not be concealed satisfactorily with paint, but made ob- =viousand objectionable breaks in the smooth surface. Compressing the shellinto the hub ;also proved a failure. My invention overcomes thesedifficulties by aifordiug a secure fastening for the shell which willnot work' loose, requires only a single small Opening in the shell, andwhen completed is entirely concealed. Briefiy stated, I fasten on eachof the shells in the following manner; An -annular groove is turned inthe external surface of the tapering end of the hub. The .tapering shellhas an internal annular rib, smaller than the groove and arranged atsuch a point on the shell that when the latter is slipped upon the hubthe rib passes over the outer edge of the groove and comes to restconcentricwith the groove, when the shell is pressed on tightly` Thegroove is then filled with molten metal poured through a small hole inthe shell. When the metal cools, the rib lies embedded in it, and theshell is firmly locked to the hub. Furthernore, the metal adheres to theinside of the slell and practically forms a large rib engaging with thegroove, so that the shell cannot come off even under the Severe-stclinatic conditions.

In the drawings, Figure 1 is a side elevation, partly in longitudinalsection, of ahub embodying my invention. Fig. 2 is a View of one end ofthe hub with the shell removed. Fig. 3 is a cross-section of Fig. 1 outhe line wa).

The hub may have the usual box A, surrounded by the wooden body or hubproper, B, containing nortises b for the spokes C. The wooden portion Bhas tapering ends, which are covered by the frusto-conical metallicshells D. In the tapering sui-face of each end of the hub is an exte'nalannular groove b', the outer edge of which is naturally of smallerdiameter than the inner edge, owing to the fact that it is nade in atapering or conical Object. Each shell D has an internal ann ular rib(Z,the inside dia meter of which is greater than the diameter of theouter edge of the groove. When the shell is pressed tightly on the hub,the rib passes freely over the groove and stands concentric with it, asclearly shown in Fig. 1. A small hole is bored through the shell intothe groove, and,molten metal E is then poured-in through this hole untilthe groove is full pletely surrounded. This locks the shell firnly tothe hub by a concealed fastening, the only visible indication of whichis the small sprue e, filling the hole d'. This is easily covered withpaint when the hub is finished.

I an aware that it has been proposed to secure'bands to hubs by pouringmolten metal into a groove adj acent to one edge of the band or througha hole in the band into a cavity in the hub; but in both cases there isuo internal projection or rib on the band with which the metal in thegroove or cavity interlocks, as set forth in the foregoing descriptionof myinvention and expressly mentioned in the following claims.

Having thus describedmy invention, what I claim, and desire to secure byLetters Pat ent, is-- 1. The combinatin with a grooved hub, of

and the rib is coma shell thereon provided with a rb conoentric withsaid groove, and metal filling said groove and surronnding the rib.

2. The combinaton With ahub having one or more tapering ends providedwith an eX- ternal annular groove, of a tapering shell having aninternal annular rb adapted to' pass freely over said groove, and metalfiliing said groove and surrounding said rib.

3. The conbination With a, hub having ,an

ex-ter'nal groove, of a shell having an internai A EDWARD SENDELBAOH.
